Here’s a strange one, but definitely something you should be looking out for.
It seems reputation chests, such as the new Mother’s Gift ones, can be accidentally salvaged! As barbebleuh unfortunately found out, if you leave them in your inventory, they get salvaged along with everything else, even when you only salvage common items! And it’s not like they salvage into anything useful either.
So open up those chests immediately, or just be careful when salvaging!
